Maybe this is the trap i fell into. So are you saying it is not a dual
port memory mapped into two CPUs physical address space? In another
email there was reference to shm. That would be a VMM equivalent, a
bunch of pages mapped into two processes address space.

This comes back to the lack of top level architecture documentation.
Outside reviewers such as i will have difficultly making useful
contributions, and seeing potential overlap and reuse with other
systems, without having a basic understanding of what you are talking
about.
